|Common Name(s)||Swamp Oak|
"Tree 8-20 m high or rarely shrub to c. 2 m, frequently producing root suckers. Bark finely fissured and scaly, grey-brown." (Flora of Australia)
All Casuarina spp. are dioecious except C. equisetifolia.
Within the Family Casuarinaceae, leaves are modified down to "teeth" observable as whorls. The whorls are located between portions of the branchlets, the portions being referred to as "articles". Casuarina glauca has 12-17, rarely 20, teeth at the junctions of the articles. Photographs below show these morphological features. "Grows in brackish situations along estuaries and streams, usually near the coast but somewhat farther inland along the Clarence, Hunter and Hawkesbury R. valleys; often forming pure stands as an open forest or woodland." (Flora of Australia)
Seed collection in scale from this species requires lopping of branches and handling of that material on to drying tarps. Field drying is far more efficient if at all possible because a considerable bulk of material may be required to generate quantities of seed. The branches are relatively heavy. Care is required not to lose too many cones to the ground when lopping takes place. The cones may dislodge easily.
"Occurs from Yeppoon, Qld, S to Bermagui, N.S.W." (Flora of Australia)
